Design Considerations of CinemaScope Film

E. I. Sponable, H. E. Bragg, L. D. Grignon

This paper pertains to a new design of 35mm film for release purposes. The design was executed specifically for use in presentation of pictures by the Cinema-Scope system, but there is nothing which prevents the application of the film to other types of motion-picture methods. The essential features of CinemaScope film are a new, smaller perforation, and a change in the perforation transverse spacing. By this means, additional area is made available for a picture image of greater size than presently used, and for four magnetic soundtracks. The net result is an arrangement which makes for the maximum use of conventional width. The analyses, reasoning and other considerations which culminated in the design described are given in detail.
